Implementation Of Flash Adc Using Multisim Technology

Transcript

Resolution, Speed, and Power consumption are the three key parameters for an Analog-to-Digital Converter (ADC) and Flash ADCs are the fastest type of ADC. In this paper an effort is made to design 3-bit and 8-bit Flash ADC using multisim. Flash ADC very useful for high-speed applications such as radar detection, wide band radio receivers and communication links. More often the flash ADC is embedded in a large IC containing many digital decoding functions. The integrated flash ADC is operated at 3 and 8-bit precision with analog input voltage of -10.0Vdc to +10.0Vdc. The ADC has been designed, implemented & analysed using Multisim tool and this paper provides a detailed view of a 3 bit and an 8 bit Flash ADC using comparators, 7segment display (Hex value) and actual working explanation about Flash ADC with step by step accurate simulated output using Multisim. The simulated output shows higher range of accuracy (seven digits) is obtained when Flash ADC is experimented in Multisim. Multisim offers additional features such as ease of implementation, rebuild and cost reduction when compared to practical simulation of Flash ADC.
